C0180: Machine serial number mismatch
Machine serial number mismatch between the main and engine side when turning the power on.
2 Checking the machine
serial number in the
EEPROM on the main/
engine PWB
The EEPROM for the dif-
ferent main unit is
installed.
Check the main and engine
machine serial number in
U004 and if the engine num-
ber is different, install the cor-
rect EEPROM in the main/
engine PWB.
3 Replacing the main/engine
PWB
The main/engine PWB is
faulty.
Check the main and engine
machine serial number in
U004 and if the main number
is different, replace the main/
engine PWB and execute
U004.
4 Checking the EEPROM The EEPROM is faulty. Check the main and engine
machine serial number in
U004 and if the engine num-
ber is different, reinstall the
EEPROM in the main/engine
PWB. If not repaired, replace
the EEPROM and execute
U004.
Note: Do not execute U004
(selecting [Execute] and
pressing the [Start] key). A
different machine serial num-
ber is overwritten.
4 Replacing the main/engine
PWB
The main/engine PWB is
faulty.
Replace the main/engine
PWB.

1 Checking the machine
serial number in the
EEPROM on the main/
engine PWB
The main/engine PWB for
the different main unit is
installed.
Check the main and engine
machine serial number in
U004 and if the main number
is different, attach the correct
main/engine PWB.
2 Checking the machine
serial number in the
EEPROM on the main/
engine PWB
The EEPROM for the dif-
ferent main unit is
installed.
Check the main and engine
machine serial number in
U004 and if the engine num-
ber is different, install the cor-
rect EEPROM in the main/
engine PWB.
3 Replacing the main/engine
PWB
The main/engine PWB is
faulty.
Check the main and engine
machine serial number in
U004 and if the main number
is different, replace the main/
engine PWB and execute
U004.
